Windspeed symbols FI

Windspeed symbols

Wind is indicated in increments of 5 knots (kts), with the outer end of the symbol pointing toward the direction from which the wind is blowing. The wind speed is determined by adding up the total of flags, lines, and half-lines, each of which have the following individual values:
Flag: 50 kts
Line: 10 kts
Half-Line: 5 kts
A knot is a speed of 1,852 km / h.

Example:

wind_speed_25kn Means 25 kts from the West

 

Symbols Knots (kts), km/u)
wind_speed_00kn 0 kts, 0 km/u
wind_speed_05kn 5 kts, 9 km/u
wind_speed_10kn 10 kts, 19 km/u
wind_speed_15kn 15 kts, 28 km/u
wind_speed_20kn 20 kts, 37 km/u
wind_speed_25kn 25 kts, 46 km/u
wind_speed_30kn 30 kts, 56 km/u
wind_speed_35kn 35 kts, 65 km/u
wind_speed_40kn 40 kts, 74 km/u
wind_speed_45kn 45 kts, 83 km/u
wind_speed_50kn 50 kts, 93 km/u
wind_speed_55kn 55 kts, 102 km/u
wind_speed_60kn 60 kts, 111 km/u
wind_speed_65kn 65 kts, 120 km/u
wind_speed_100kn 100 kts, 185 km/u
wind_speed_105 kn 105 kts, 194 km/u
 

The wind symbol points to the direction the wind is coming from and the wind blows from the flag to the symbol for the clouds (which is located at the location of the weather station).

The knot is a unit of speed that is widely used in shipping and in motorized aviation. A knot is one nautical mile per hour. A nautical mile is defined as exactly 1852 meters. A knot is thus a speed of 1,852 km / h. Since a knot is already a speed (traveled distance per unit of time), it is wrong to speak of ’knots per hour’. In aviation, English is the official language and one speaks of knot (s) (pronounced as nott (s)).
